Technical modifications
Modifications may be carried out on your vehicle
only if approved by Porsche.
This ensures that your Porsche will remain reliable
and safe to drive, and that it will not be damaged
as a result of the modifications.
Your Porsche partner will be pleased to advise
you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
Porsche partner or a qualified specialist
workshop. Accessories which are relevant to
safety should not be used unless they have
been obtained from the Porsche Tequipment
product range or have been tested and
approved by Porsche. Your Porsche partner
will be pleased to advise you and answer any
of your questions.
However, the use of other parts or accesso-
ries may adversely affect the safety of your
vehicle, and Porsche can take no responsibility
for any loss or damage caused by their use.
Even if the supplier of other accessories or
parts is a recognised supplier, the safety of
your vehicle may still be affected if such items
are installed. Due to the large variety of
products offered in the accessory market, it is
not possible for Porsche to inspect and
approve every one.
f In addition, please note that the use of replace-
ment parts which are not approved by Porsche
may also detrimentally affect the Warranties
relating to your vehicle.
f
Regularly check your vehicle for signs of
damage.
Damaged or missing aerodynamic compo-
nents such as spoilers or underside panels
affect driving behaviour and must therefore be
replaced immediately.
Setting and operating vehicle
components when driving
Warning!
Operating the on-board computer, the radio,
the navigation system, the telephone or other
equipment while driving is dangerous and
can result in an accident.
This could distract you from the traffic and
cause you to lose control of the vehicle.
f
Operate these components while driving only if
the traffic situation allows you to do so safely.
f Carry out any complicated operating or setting
procedures only while the vehicle is stationary.
Porsche Ceramic Composite Brake
(PCCB)
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
may therefore cause the brakes to squeal.
Wear on different components of the braking
system, e.g. brake pads or brake discs, depends
to a great extent on the individual driving style and
the conditions of use and therefore cannot be
expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear
increases considerably when the vehicle is driven
on race tracks or through an aggressive driving
style.
f Before using your vehicle in this way, please
consult your Porsche partner about the guide-
lines which currently apply.
